Kicking off the 2022 Gila monster breeding season seemed like a time to start our YouTube videos. We plan on documenting the entire breeding season, from warm up to hatching babies, to help expand the knowledge of breeding Gila monsters in captivity. Check it out here and let us know what you think!
This photo shows offspring produced here over a three-year period; 2019-2020-2021. They really start to chunk out after the second year, but still have some growing to do!
Here are some highlight of our baby Gila monsters hatching this year. Eggs incubated 142 days at 80.5°F.
The 2021 baby Gila monsters are all out and settling in here at Goatsby’s Place! We are very proud of our beautiful baby monsters, and feel blessed to have been successful again this year. While most are spoken for, we may have a few available for new homes. Please email us if interested, or to get on the list for 2022.
I have always loved Halloween, but for the past two years our Gila monsters have been hatching on this magical day which delights me too no small end. HAPPY HALLOWEEN!
With the discovery that hatchling Gila monsters over winter in their nest, I wanted to perform my own non-scientific social study of hatchling Gilas. Normally baby Gila monsters are reared on their own in solitary containers to facilitate easier feeding and maintenance, but this year I housed two siblings to see how they would be together. While they were housed alone for for the first two months to ensure both were feeding regularly and healthy, they were introduced into an adult-sized terrarium and have been there ever since. So far? The photo above best describes the behavior from the hatchlings. The definitely tend to share the same “burrow” / hide more often than not, and are active at the same time. Feeding has to be done carefully so as to ensure there is not fighting over food.
I do not know if there is a certain age they go their own way, but I will keep they together through the first year to see how they act with each other. Seeing this and the behavior of my adults makes me wonder about the social structure of these reptiles. There truly is still so much to learn about Gila monsters!
Check here for the scientific findings from the discovery above.
Though work and the other parts of my life have kept me from updating this blog on a regular basis, working with the Gilas has not slowed down. As of today my females are gravid and have gone through their pre egg-laying shed so oviposition is expected within the next week, according to my calculations.
This year my nesting protocol has changed due to the failures (or, opportunities for learning) of last year. last year one of my females delayed egg laying by about 10 days which resulted in the death of six viable eggs. Not a very fun lesson but certainly an opportunity for improvement. I think last year the female did not have the proper secure nesting area and held her eggs until she could not hold them any longer. I also tried a new nesting material which did not work out very well as it did not hold moisture for very long. This year, things have changed.
To help increase privacy and to solve the humidity issue everything has been changed. To start, the entire cage has been converted to a nest box. This is to allow the females to continue to thermoregulate (though over lower temperatures) throughout this period. I have installed privacy tint on 1/2 of the cage as well as a large black hiding box to increase privacy. I also went back to good old sphagnum moss misted daily to help maintain moisture in the cage. The ultimate goal is to provide a secure area that matches conditions for positive egg growth. So far it appears to be working as the conditions in the cage mirror those in my incubator (see below screenshot from my SensorPush app).
Will this ultimately work? We will know within two weeks. If all goes well my females will lay viable eggs this year. If not, I’m sure there will be a lesson learned and opportunity for improvement next year! Fingers crossed!
It’s mid-February, the adult Gilas are slowly coming out of hibernation, the 2020 babies are going to new homes, and to say we are excited about the 2021 season is an understatement! This year we have an ultrasound that will help us improve breeding and oviposition, and we will share some information on this here once we can successfully figure it out:$ If you are interested in getting on the list for 2021 or just want to discuss monster, drop us a message!
In case you haven’t seen them, here are 2020’s babies!
These Gila monsters were holdbacks from my 2019 season. It is amazing to see the changes in pattern and color over the year since they were born!!
My 2020 Gila monster season is off and running. After reviewing my data and re-reading my Gila books, I was going to wait until after April 1 this year to pair the Gilas as that is when the magic happened (and seems to be for others as well). With the Shelter-in-Place order in full effect I got bored and but them together last weekend, and guess what? No activity yet. What I have found interesting is that the Gilas seem to remember each other from last year and there was no fighting between the pairs (females bit males for being too pushy). This year they are much more chill, and are spending time together the hide boxes. I have been checking in at night to see what is going on and while both Gilas are active, copulation has not yet been observed. Being a Nervous Nelly, I am concerned that they will not breed this year but will hold my real worry for late April
To me, the real question is could Gila monsters mate for life? I’ve read that in the wild males go back to the same shelters where they have previously copulated and in my observations females certainly do prefer some males over others. The way they rest together and spend time with each other makes this is an interesting avenue to explore. Some breeders swap different females in male cages and have great success, but I am going to try leaving known pairs together to see how things go. I can see why having one pair of Gilas could be difficult to breed and that groups (3.3 or greater) are suggested.
As with all things, time will tell. New observations, and hopefully some activity, will be reported here. Stay tuned..
Answer: Male on left, female on right:)
